Improved Computational Target Site Prediction for Pentatricopeptide Repeat RNA Editing Factors
Pentatricopeptide repeat (PPR) proteins with an E domain have been identified as specific factors for C to U RNA editing in plant organelles. These PPR proteins bind to a unique sequence motif 5' of their target editing sites. Recently, involvement of a combinatorial amino acid code in the P (normal length) and S type (short) PPR domains in sequence specific RNA binding was reported. PPR protei...
متن کاملChloroplast RNA editing by pentatricopeptide repeat proteins.
Pentatricopeptide repeat (PPR) proteins function in multiple processes in mRNA maturation in plastids and mitochondria (reviewed in Schmitz-Linneweber and Small, 2008). RNA maturation in chloroplasts is complex, and PPR proteins act in cisand trans-splicing, translation, RNA cleavage, RNA stabilization, and RNA editing. This large protein family, with 450 members in Arabidopsis, is characterize...
متن کاملPentatricopeptide repeat proteins involved in plant organellar RNA editing
C-to-U RNA editing has been widely observed in organellar RNAs in terrestrial plants. Recent research has revealed the significance of a large, plant-specific family of pentatricopeptide repeat (PPR) proteins for RNA editing and other RNA processing events in plant mitochondria and chloroplasts. PPR protein is a sequence-specific RNA-binding protein that identifies specific C residues for editi...
متن کاملRice OGR1 encodes a pentatricopeptide repeat-DYW protein and is essential for RNA editing in mitochondria.
RNA editing is the alteration of RNA sequences via insertion, deletion and conversion of nucleotides. In flowering plants, specific cytidine residues of RNA transcribed from organellar genomes are converted into uridines. Approximately 35 editing sites are present in the chloroplasts of higher plants; six pentatricopeptide repeat genes involved in RNA editing have been identified in Arabidopsis...
متن کاملComputational prediction of RNA editing sites
MOTIVATION Some organisms edit their messenger RNA resulting in differences between the genomic sequence for a gene and the corresponding messenger RNA sequence. This difference complicates experimental and computational attempts to find and study genes in organisms with RNA editing even if the full genomic sequence is known. Nevertheless, knowledge of these editing sites is crucial for underst...
